“…The COPs yield initially increased, and then decreased with the increase of ultrasound power ( X 1 ) and extraction time ( X 4 ). The interaction of caused by ultrasound power ( X 1 ) and extraction time ( X 4 ) in this study is consistent with Gu et al (2020) studying on ultrasound assisted extraction polysaccharides from Sagittaria sagittifolia L [34] .

“…This band could be used as an indicator of the presence of pyranose; [35] The absorption peak at 879 cm −1 fell at 890-840 cm −1 , which was the -anomeric of the pyran ring, indicating that CHP-2 contains monopyranose. [36]…”

“…Since the molecular weights of polysaccharides were too large, the 13 C-HMR spectrum overlapped and did not show characteristic absorption peaks, however, absorption peaks did appear at 170-180 ppm, indicating the presence of uronic acid, [10] Since the main component of CHP-2 is glucose, combined with 1 H-NMR and 13 C-NMR analysis, it was inferred that the absorption peak could be assigned to →4)--D-Glc(p)-(1→), →t)--D-Glcp-(1→).

Four new types of water‐soluble polysaccharides are isolated from Cardamine hupingshanensis. Herein, this study examines C. hupingshanensis polysaccharide no. 2 (CHP‐2) with a molecular weight of 21.75 kDa. Analysis revealed that CHP‐2 is composed of d‐glucuronic acid, d‐galacturonic acid, glucose, galactose, and L‐arabinose. It is speculated that the main connecting bond is →4)‐α‐D‐Glc(p)‐(1→), →t)‐α‐D‐Glcp‐(1→). Through perfusion experiments using streptozotocin‐induced diabetic rats, oral CHP‐2 solution is found to significantly reduce food intake, water intake, and fasting blood glucose levels, while increasing the weights of rats. In addition, CHP‐2 significantly reduces the serum and liver malondialdehyde contents and increases the activity of the corresponding antioxidant enzymes. Moreover, the effect elicited by the CHP‐2 solution is similar to that of phenformin hydrochloride solution. Hence, the results of this study suggest that CHP‐2 exhibits blood sugar‐lowering and anti‐oxidation effects.

“…This wide bands correspond to the hydroxyl groups with intermolecular hydrogen bonding, which mean that there are a lot of intermolecular hydrogen bonds in the LSEP, thus affecting the viscosity of the polysaccharide solution. The absorption peak at 2931.08 cm −1 was caused by the asymmetric stretching vibration of the C-H bond in the alkyl group of the polysaccharide chain structure [21]. The band at 1639.63 cm −1 was attributed to the asymmetric stretching vibration of the C=O bands [22].…”

The present study aimed to evaluate the rheological and interfacial behaviors of a novel microbial exopolysaccharide fermented by L. starkeyi (LSEP). The structure of LSEP was measured by LC-MS, 1H and 13C NMR spectra, and FT-IR. Results showed that the monosaccharide composition of LSEP was D-mannose (8.53%), D-glucose (79.25%), D-galactose (7.15%), and L-arabinose (5.07%); there existed the anomeric proton of α-configuration and the anomeric carbon of α- and β-configuration; there appeared the characteristic absorption peak of the phosphate ester bond. The molecular weight of LSEP was 401.8 kDa. The water holding capacity (WHC, 2.10 g/g) and oil holding capacity (OHC, 12.89 g/g) were also evaluated. The results of rheological properties showed that the aqueous solution of LSEP was a non-Newtonian fluid, exhibiting the shear-thinning characteristics. The adsorption of LSEP can reduce the interfacial tension (11.64 mN/m) well and form an elastic interface layer at the MCT–water interface. Such functional properties make LSEP a good candidate for use as thickener, gelling agent, and emulsifier to form long-term emulsions for food, pharmaceutical, and cosmetic products.
